“…In fluorescein iris angiography, during the arterial phase, fluorescein first fills the nasal side, and then fills the temporal side 8. A possible explanation of this finding was reported by Amalric and Rebiere18 who explained that the preferential filling was due to the distribution of blood vessels being most dense in the superior-nasal sector.…”

“…A possible explanation of this finding was reported by Amalric and Rebiere18 who explained that the preferential filling was due to the distribution of blood vessels being most dense in the superior-nasal sector. In addition, Hayreh and Scott8 showed that blood vessels were evenly distributed in all areas, but in some eyeballs the blood vessels might be more densely distributed in the nasal side.…”

“…Thus, studies on the iris vascular network have been previously conducted. However, most anatomical studies on the human iris vascular network have been performed in vivo with fluorescein iris angiography 4,7,8. Other studies have been conducted in vitro and were performed with scanning electron microscopy after the injection of resin into the human iris vascular network 9-13…”

PurposeThis study was performed to examine the vascular network of the human iris using flat preparation.MethodsThe ciliary body-iris structures were separated from human eyeballs, and a portion of the irises were treated with trypsin to remove the pigment granules. These iris tissues were unfolded and placed onto glass slides using flat preparation, and the vascular network of each iris was examined by fluorescein microscopy. The ciliary body-iris structures separated from the remaining eyes were stained with hematoxylin-eosin without trypsin treatment and were examined by light microscopy.ResultsThe long posterior ciliary artery formed several branches before entering the iris root, and such branches formed the major arterial circle of the iris with diverse diameters in the vicinity of the iris root and the ciliary process. In the pupillary margin, the iris vasculature network formed a cone shape and then formed an arcade by connecting to adjacent vasculatures. In the vicinity of the collarette, the iris vasculature network formed the minor arterial circle of the iris with diverse diameters perpendicular to the arcade of the iris network located in the pupillary margin. In the pupillary margin, the capillaries were somewhat thick and connected to the irregular traveling iris vein.ConclusionsThe above findings explain the human iris vascular network and provide a theoretical basis for the sectoral filling of the iris vasculature seen in fluorescein iris angiography.

“…For this purpose, methods such as fundus fluorescein angiography, iris fluorescein angiography, indocyanine green angiography, arteriography, venography, ophthalmodynamometry, pneumoplethysmography, suction-cup dynamometry, oculooscillodynamography, marked microspheres, and laser Doppler velocitometry have been used previously. 6,[10][11][12][13][14][15][16] More recently, color Doppler ultrasonography has been found to be beneficial in investigating the changes of retrobulbar blood flow after some ophthalmic surgical procedures such as scleral buckling, trabeculectomy, and optic nerve decompression. [17][18][19][20] Although anterior ciliary arteries and anterior segment circulation cannot be assessed with conventional Doppler equipment, potential alterations in retrobulbar blood flow after strabismus surgery can be evaluated by this method.…”

“…[1][2][3] During conventional rectus muscle surgery, the anterior ciliary arteries are not preserved because anterior segment ischemia does not occur in healthy subjects with routine horizontal rectus muscle surgery. 1,2,[4][5][6] On the other hand, combined vertical and horizontal rectus muscle interventions have a higher risk for development of anterior segment ischemia. [1][2][3][4][5] After the recession or resection of rectus muscles, anterior ciliary arteries do not recanalize.…”
